I once lost the key to the US Capitol building. As in, the huge marble building that houses the US Congress.

Well, not literally the key to the Capitol (there is no such thing) but the master key to one of the office wings. At the time, I worked for a very important member of the Congressional leadership (a person you see on TV all the time in the US), and I thought for sure the Chief of Staff would fire me when I told him.

Nope. Turns out this happens all the time. Within an hour, a crew of servicemen had replaced every knob in that wing and everybody on staff had new keys by the end of the day. They joked, we always keep extras because the members of Congress lose these things like crazy.

True story.
